ENVIRONMENTAL ENGINEERING

Course Objective

It will be learned the principles governing physical behavior of pollutants in the environment and in contaminant removal processes. Lectures cover the development of relevant theoretical concepts up to the point where, in homework and example problems, they can be applied to practical applications. As indicated in the course syllabus, the topics concern colloidal and particulate matter in environmental systems; mass transport theory applied to environmental systems; and other interfacial phenomena that are important in environmental systems.

Learning Outcomes of the Course Unit

1   Definability of pollutants in the environment
2   Describability of physical behavior of the pollutants in the environment
3   Describability of physical behavior of the pollutants in the contaminant removal processes
4   Definability of colloidal and particulate matter in environmental systems and mass transport theory applied to environmental systems
5   Definabaility of the importance of physical processes in Environmental Engineering

Further Notes About Assessment Methods

Assessment of student progress regarding the course objectives will be made through continuous private communications during the semester with students and through mid-term examinations and homework assignments. Cumulative assessment will be addressed through standard course evaluations at the end of the semester.

Assessment Criteria

The method of evaluating the progress will be through homework (15%), first mid term exam (17.5%), second mid term exam (17.5%), final exam (40%), and class participation (10%)

Language of Instruction

English

Course Policies and Rules

Students will need to understand differential equations and vector calculus to follow the lectures, although less fluency in these is required to complete most of the homework and test questions. Previous courseworks in environmental engineering is recommended in order to place the course topics into proper context.
